IMPROVEMENT IN MECHANICAL MOVEMENTS.

Specification forming part of Letters Patent No. 178,062, dated May 30, 1876; application filed April 25, 1876.

To allwhom it may concern:

vibratory motion.

The invention consists-in the combination of the shaft, the three-armed cam, and one or more notched and pivoted triangular blocks with each other and with their inclosing-case, for converting a rotary into a "ibratory motion, as hereinafter fully described.

The case consists of two circular plates, A, attached to a hoop or flange, B, by which they are kept at the proper distance apart. To the center of the plates A is pivoted a shaft, 0, to one end of which the power is applied. To the shaft 0, within the case A B, is rigidly attached a threearmed cam, D. To the case are pivoted one, two, or three blocks, E, which are made triangular in their general form, and

are pivoted at their angle. The third sides of the blocks E are turned toward the cam D, r

and are notched in sucha waythat, as the said cam revolves, each of its arms will strike the first arm of block E, push it back, enter the notch of said block, strike its other arm, and push it forward, so that each block will receive six distinct impulses at each revolution of cam D.

Motion maybe communicated from the block E to the object to bevibrated by an arm, F,

formed upon, or rigidly attached to, the said block at its pivoted angle, as indicated at the left-hand side of the figure, or by connectingrods pivoted to the ends of the arms of said blocks, as indicated by the pins G at the righthand side of the figure.

Having thus described our invention, we-
